Is there any real reason behind DST? Personally, I think it's just to keep us on the edge of our seats. Oh, yea, and why was it moved a month early this year?

This one's not for kids. There are 12 coins. One of them is slightly heavier or lighter than the others. You have a classical balance with two pans (which only indicates which pan is heavier/lighter). You are allowed to weigh only three times. Can you find out the coin which is different, and also whether it's heavier or lighter?

i need to be able to experiment it and have a hypothesis and everything else. i hate the ones that science sites give because they are so hard to search and most cannot be experimented. are there any you have done in the past that are good?

He derived it while porking two underaged girls whom he impregnated. This is a serious question and not the rantings of a pervert. My point is, at what price should we accept scientific discovery.

So for science class, I have to invent something, anything, that hasn't been invented before. Everybody in my grade is doing it.
The rules:
you have to make sure it has never been created before
you have to make it
IT DOESNT HAVE TO WORK, but there must be a model
and it has to be something that could actually work

i used to have a partner, and tomorrow we were going to work on our idea and stuff. but just 5 minutes i called my partner to ask her where to meet and she said "oh right, um well see heres the thing, im doing it with somebody else" than she said bye and hung up!
so i am partner-less!
i am no good at making anything, but clothes!
so i have no idea what to do, and i cant get a partner now cause everyone already has one.

please, anybody, please please help with an idea of something i could invent!
also, anything else that you could tell me that would help me!
just remember, im in middle school

thanks so much!!!!!

I am currently in high school and we are choosing courses for next year. If I want to pursue a career in the science/math direction, should I still take AP english/history courses? My interest lies in math and science, but my grades are equally as high in all areas. What I am sure to be taking are: Precalculus Honors, AP Biology, and Spanish Honors. I am not sure if I should take AP English and/or AP History. Any advice from any one with a career in math/science?

Both the man and the woman agreed they used a condom. The show quoted the chances of a condom failing are one in a hundred. Then they revealed the paternity test done on an unborn baby naming the man as the father. The chances of the paternity test being correct were quoted as 9 out of ten. Correct me if im wrong but doesn’t this mean if 100 men have sex all using a condom only one will fail, but if all the woman get pregnant and paternity test are done on all the men at least ten of the paternity tests will be wrong.

Surely there was still only a one in ten chance he was the father
